[0002] A traditional trailer refers to a vehicle towed by a car but without its own power drive device. It is a combination of a car and one or more trailers, and is driven by the power provided by the main car. The truck and the towing car are the driving sections of the car train, called the main car, and the driven section towed by the main car is called the trailer. It is an important type of vehicle for road transportation. Using car train transportation is the most effective and simple means to improve economic efficiency, and can easily realize section transportation.
